Hi @umesh.javir_84. What do yo mean by 'update'? There is a tool button named "Regenerate All Rules" on the Manage tab, iLogic panel. When you click that, it will regenerate and run all rules in the current document, and all the rules in any referenced documents. This is mainly to reconnect broken links with parameters named within the rules. Or do you mean that you want to change the contents of the rules, such as having one rule that has the correct contents (text) and wanting to overwrite all other rules with the same name with the same contents? Please explain what you want in more detail.
